Crypto security incidents generated $6.48 billion in reported losses across 56 major events in October 2026, a roughly 745% jump from September that was driven largely by a Binance incident.

October’s reported losses rose from $766.49 million in September 2026. The Binance event accounted for roughly $6.3 billion, making it the largest crypto security incident of 2026 to date. $3 billion in assets tied to the event had been frozen.

Bitget ranked second, at $387 million, followed by Liquid Network at $320 million. $285 million tied to the Liquid Network incident had been recovered. The figures do not provide a combined net-loss total after freezes and recoveries.

By Oct. 31, the 10 largest attacks of 2026 totaled $8.6 billion, or 92.3% of the year’s losses. That tally had not deducted frozen or recovered funds. Drift, KelpDAO/LayerZero and COLDCARD Wallet also ranked among the year’s top 10 attacks.

Binance Hack: $6.3 Billion Stolen in Largest Crypto Security Incident On November 1, 2026, Binance disclosed a hack that resulted in the theft of $6.3 billion, marking the largest crypto security incident in history. The breach was attributed to hackers accessing an engineer's laptop and gaining control of the exchange's digital wallets. Following the attack, $3 billion in stolen assets were frozen by Tether, Circle, and other firms, leaving approximately $3.3 billion still under the hackers' control. Binance has committed to covering the losses to customers, despite its Secure Asset Fund for Users (SAFU) holding only $1.2 billion at the time. As of November 2, Binance reported that it has replenished 95% of the stolen assets and has begun restoring withdrawals in phases, starting with major cryptocurrencies like Bitcoin and Ether. The incident has raised concerns about the security of centralized crypto exchanges and the concentration of assets within a few platforms. 3 sources 66
